I have 2003 Ford Mustang with 147,000 miles, the car only drives when its in reverse and no other gears. The gears shift easily. I recently added new transmission fluid into the car bc there wasnt any but before I did that I did drive it on the highway for about 30-40 minutes to get to my local auto shop. Before this the car was sitting for about 2-3 weeks. Just wondering what part of the transmission that can possibly be failing or do i need to get my car trans. fluid entirely flushed?

Gears stays in place once I change them My car has 147000 miles.
My car has an automatic transmission.
